ASC Engineered Solutions 310070800 – Frequently Asked Questions
1) Are all four openings on the ASC 2 inch black malleable iron cross the same size?
All four outlets are 2 inch, female pipe thread, so it's a straight cross with no reducing branches. Threads are cut to ASME B1.20.1 (NPT), so it mates with standard 2 inch threaded steel or iron pipe and 2 inch male threaded nipples.
2) Can I use a black malleable iron cross on a potable water line?
No. Black malleable iron is for non-potable service, dry systems, gas, and fire protection piping. Water lines corrode it from the inside. For potable water in threaded iron, use a galvanized fitting instead, and check your local code, since many jurisdictions now require copper, CPVC, or PEX for potable branches.
3) Is this a Class 150 standard cross or an extra-heavy fitting?
Standard strength (STD), which in malleable iron threaded fittings is the Class 150 pattern under ASME B16.3. If your drawing calls for Class 300 extra-heavy, this is not the fitting for that spec.
4) What is the part number and weight on the ASC 2 inch black cross, for my submittal and material takeoff?
Order it as ASC Engineered Solutions model 310070800. Each fitting weighs 3.3 lbs, which is worth counting if you're hanging a run of these on trapeze or clevis supports. Material is malleable iron to ASTM A-197.
5) Should I use a cross or two tees where four 2 inch pipes meet?
A cross puts all four branches on one centerline pair at a single point, so it saves a pipe nipple and keeps the assembly compact, which matters in tight riser closets and on sprinkler cross-mains. Two tees back to back offset the branches, which you want when you need the takeoffs staggered or when you want to rotate one branch independently. Since all four outlets here are 2 inch FPT, the cross only works when every leg is 2 inch threaded pipe.
6) Will this cross thread onto grooved or plain-end 2 inch pipe?
No. All four ends are female NPT to ASME B1.20.1, so the pipe has to be threaded. Grooved-end pipe needs a grooved cross and couplings, and plain-end pipe has to be cut and threaded first (or joined with a plain-end mechanical fitting).
7) Do I need thread sealant with this malleable iron cross, or does it seal on its own?
NPT threads to ASME B1.20.1 seal on the taper but still need a sealant to be leak-tight in service. Use PTFE tape or a pipe thread compound rated for the medium you're running, and nothing is supplied with the fitting.
